Possibly, but it won't be easy.
EMC2 can be used without expensive hardware, but to get the best performance, some machines may need a hardware assist. Some people even make their own stepper drives to save money.

I am not in this to give everything away, I hope to make a small amount of money out of it. I also build nuclear research electronics, and I charge a LOT more for that gear than I charge for the CNC stuff. If you compare my prices to much other equipment of similar size/component count, you will see I am making my prices quite competitive. If you like Mesa's products or prices better, you can use theirs. I don't know how they make stuff at the prices they do, I can't get close to $79 for just about any board with more than a couple chips on it. But, unless you are an electronics expert, you may find building a board with an FPGA quite difficult to do at home, and then you will have to test and debug it, too. This is not typical home hobby stuff to work with, many of these parts have lead pitches of 0.65 to 0.5 mm.
